Abstract

Leading-edge wing planform variations modeled after protuberances seen on humpback whale ippers are believed to result in improved lift and drag characteristics in the near-stall regime. The unconventional geometry makes ow predictions highly sensitive to turbulence models which are otherwise well validated for conventional wings at high Reynolds numbers. We carry out a computational study aimed at validating a RANS approach for the analysis of tubercles in a Reynolds number range 62,500-500,000. Comparisons with experimental observations are presented and the relevant ow physics are discussed.
